Alkaline earth metal salts of aziridine-2-carboxylic acid, typically Ca salt, are produced by a reaction of a 2,3-diha- iopropionic acid derivative or an a-haloacrylic acid derivative with an aqueous ammonia in the presence of an alkaline earth metal hydroxide, typically Ca(OH)2.
Salts of aziridine-2-carboxylic acid are recovered from such a reaction product as referred to above by a liquid chromatographic technique in which a weak or weakened cation exchanger is utilized.
氮丙啶-2-羧酸的碱土金属盐,通常为 Ca 盐,是由 2,3-二哈-碘丙酸衍生物或 a-卤丙烯酸衍生物与水氨在碱土金属氢氧化物(通常为 Ca(OH)2)存在下反应生成的。
